Skyrim’s hugely-anticipated debut DLC expansion Dawnguard will last gamers a minimum of ten hours, according to Lead Artist Matt Carofano.

“It’ll take between ten and 20 hours to beat,” he told Game Front at E3, adding that it will last about the same amount of time as a faction quest-line.

Dawnguard will feature two narratives – one centered around vampires, the other, the vampire-hunting Dawnguard – guess that makes them around five to ten hours apiece.

“Dawnguard will be significantly bigger than any Fallout DLC,” Carofano explained. “We wanted to do something more in depth than that. It’s not as big as Shivering Isles, but there’s still a lot of content there.”

With Skyrim launching back in November, Bethesda has been working on new content for some time – including mini-improvements such as mounted combat.

Expectation for Dawnguard is high, so hopefully Bethesda is creating something pretty special.

Dawnguard is currently in invite-only beta on Xbox 360, and is tentatively due to hit the console at the end of June, following on PS3 and PC 30 days later.
